What is the formula to calculate the thermal efficiency of an Otto cycle engine?
The formula to calculate the thermal efficiency of an Otto cycle engine is: Thermal Efficiency 1 - (1 / compression ratio)
How do you determine mechanical thermal and relative efficiency?
Mechanical efficiency is determined by dividing the output work by the input work, while thermal efficiency is calculated by dividing the useful work output by the heat input. Relative efficiency is the ratio of mechanical efficiency to thermal efficiency and can be used to compare the effectiveness of a machine in converting input energy to useful work.
What are the factors of thermal efficiencyhow does each factor affect thermal efficiency?
Factors of thermal efficiency include combustion efficiency, heat transfer efficiency, and frictional losses. Combustion efficiency refers to how well fuel is converted into heat energy, while heat transfer efficiency measures how effectively heat is transferred within the system. Frictional losses occur due to resistance in moving parts and can reduce overall energy output. Improving combustion efficiency, enhancing heat transfer mechanisms, and minimizing frictional losses can all help increase thermal efficiency.
How to find thermal efficiency in a system?
To find thermal efficiency in a system, you can use the formula: Thermal Efficiency (Useful Energy Output / Energy Input) x 100. This calculation involves determining the amount of useful energy produced by the system compared to the total energy input. The higher the thermal efficiency percentage, the more effectively the system converts energy into useful work.
What is the thermal efficiency for a good boiler?
A good boiler typically has a thermal efficiency of around 85% to 95%. This means that it can convert 85% to 95% of the energy in its fuel into usable heat for heating water or spaces. Higher efficiency boilers are more cost-effective and environmentally friendly.
Is it true that thermal efficiency of a diesel engine equals indicated thermal efficiency - brake thermal efficiency?
no

What is efficiency of an engine that gives off 70 percent thermal energy?
It is not a good efficiency engine.
If efficiency of converting chemical to thermal energy was 90 percent what would the overall efficiency be?
In saying what the overall efficiency would be, I suppose you mean for other processes, creating the chemical energy for example, and using the thermal energy. This is impossible to answer, not knowing what these processes are.
